A Bethlehem Township, Pa., man was arraigned today on charges of terroristic threats after he threatened to blow up his and surrounding townhouses on Sept. 1, according to court documents.

Matthew Mark Wirth, 42, of the 100 block of Founders Court, told his wife and her mother to get out of the house so they would not be hurt about 12:30 p.m. that day, police said. At one point he dragged his wife out of the house in a headlock and locked them both outside, according to police.

Police closed down the road, and nearby townhouses were evacuated as officers used a telephone to speak with Wirth, who said he had gas and propane tanks in his basement, the affidavit said.

Wirth was arrested when he eventually came out of the house, the affidavit said. He was also charged with harassment and disorderly conduct.

He was arraigned in front of District Judge Joseph Barner and jailed in lieu of 10 percent of $10,000 bail.
